Returns HTTP 202 with a batch UUID; each file is analyzed in the background and individual results are available via `GET /detect/{uuid}` for each entry in `detect_uuids`. Two intake methods: * **Multiple media files** — repeated `files[]` form fields. * **Single zip archive** — a single `file` form field whose value is a `.zip` containing the media files. Non-media entries are skipped. Provide one of `files[]` or `file=<...>.zip` per request. Synchronous mode (`Prefer: wait`) is not supported and returns 400 if sent. Constraints: * Maximum 50 files per batch. * Maximum 500 MB total upload size across all files. * Allowed file types match `POST /detect`'s direct-upload allowlist. * Watermark analysis is not supported for batch or zip requests. Sending `detect_watermark=true` returns 400. * All-or-nothing billing: if the team's wallet cannot cover the projected cost for every file, the request is rejected with 402 and no detects are created. Reference: https://docs.resemble.ai/api-reference/deepfake-detection/create-detect-batch ## Authentication - `Authorization` header (bearer token, required) — API key from https://app.resemble.ai/hub/api ## Request ### Body (multipart/form-data) This endpoint expects a multipart form with multiple files. - `files[]` (files, optional) — One or more media files. Repeat the `files[]` field for each file. Mutually exclusive with `file`. - `file` (file, optional) — A single `.zip` archive containing media files. Mutually exclusive with `files[]`. - `callback_url` (string, optional) — POST destination invoked when the batch reaches a terminal state. - `intelligence` (boolean, optional) — Run multimodal intelligence on every file in the batch. - `infer_from_intelligence` (boolean, optional) — Opt in to let a strong intelligence finding escalate an otherwise non-fake verdict to "Likely Fake". Has no effect unless `intelligence` is also true. - `search_identity` (boolean, optional) — Run identity search against the team's saved identities (audio/video only). - `visualize` (boolean, optional) — Generate visualization artifacts. - `audio_source_tracing_enabled` (boolean, optional) — Enable audio source tracing on each audio file. - `frame_length` (integer, optional) — Window size in seconds (audio/video). - `start_region` (double, optional) — Start of segment to analyze (seconds). - `end_region` (double, optional) — End of segment to analyze (seconds). - `max_video_secs` (double, optional) — Cap processed video duration. - `use_llm` (boolean, optional) — Use LLM-assisted video analysis. - `face_only` (boolean, optional) — Focus detection on faces for video children by masking non-face regions. Audio and image children use an effective value of `false`. Retrieve each child's effective value with `GET /detect/{uuid}`; the aggregate batch response does not include this field. - `zero_retention_mode` (boolean, optional) — Enable Zero Retention Mode for every file in the batch. ## Response ### 202 Batch accepted - `success` (boolean, optional) - `item` (DetectBatch, optional) — Aggregate state for a batch detection job. Returned by `POST /detect/batch` and `GET /detect/batch/{uuid}`. ## Errors ### 400 Bad Request Error Invalid batch request (missing files, both file and files[] supplied, file count or size exceeded, unsupported file type, `Prefer: wait` header sent, or `detect_watermark=true`) - `success` (boolean, optional) - `error` (string, optional) - `errors` (map from string to list of string, optional) - `message` (string, optional) ### 402 Payment Required Error Insufficient balance for the projected batch cost. Response `details` includes per-file estimates. - `success` (boolean, optional) - `error` (string, optional) - `errors` (map from string to list of string, optional) - `message` (string, optional) ### 403 Forbidden Error Intelligence detect limit reached (Default plan). - `success` (boolean, optional) - `error` (string, optional) - `errors` (map from string to list of string, optional) - `message` (string, optional) ## Types ### DetectBatch Aggregate state for a batch detection job. Returned by `POST /detect/batch` and `GET /detect/batch/{uuid}`. - `uuid` (string, optional) — Batch UUID. - `status` (enum, optional) — Aggregate status across all child detects. - `processing` — at least one child detect is still running. - `completed` — every child detect completed successfully. - `partially_failed` — at least one succeeded and at least one failed. - `failed` — every child detect failed. - Allowed values: `processing`, `completed`, `partially_failed`, `failed` - `total_files` (integer, optional) — Number of files in the batch (1–50). - `completed_count` (integer, optional) — Number of child detects that have completed successfully. - `failed_count` (integer, optional) — Number of child detects that have failed. - `created_at` (datetime, optional) - `detect_uuids` (list of string, optional) — UUIDs of the child detects. Use `GET /detect/{uuid}` to retrieve per-file results. ## Examples **Request** ```json { "files[]": [], "file": ">" } ``` **Response** ```json { "success": true, "item": { "uuid": "string", "status": "processing", "total_files": 1, "completed_count": 1, "failed_count": 1, "created_at": "2024-01-15T09:30:00Z", "detect_uuids": [ "string" ] } } ``` **SDK Code** ```python import requests url = "https://app.resemble.ai/api/v2/detect/batch" files = { "file": "open('', 'rb')" } payload = { "callback_url": , "intelligence": , "infer_from_intelligence": , "search_identity": , "visualize": , "audio_source_tracing_enabled": , "frame_length": , "start_region": , "end_region": , "max_video_secs": , "use_llm": , "face_only": , "zero_retention_mode": } headers = {"Authorization": "Bearer "} response = requests.post(url, data=payload, files=files, headers=headers) print(response.json()) ``` ```javascript const url = 'https://app.resemble.ai/api/v2/detect/batch';
